In the early 2270's, Starfleet administered many of its operations from the impressive Orbital Office complex
above Earth.

The space station orbiting Earth is part of Starfleet's San Francisco Fleet Yards facility. In 2271, Admiral
James Kirk beamed to the orbital office complex to take a travel
pod to newly refitted USS Enterprise NCC-1701 still in
drydock.

During the 23rd century Starfleet used several orbital platforms for the production of new vessels
and modifications of existing ships. The orbital office complex supported the administrative duties while the
construction took place in drydock.

Designed with functionality and potential expansion in mind, the main visible features were four cylindrical,
copper-colored storage tanks. Beneath these was an obversation area, followed by four asymmetrical support
struts that formed corridors to a number of interlinking light-gray circular office and shuttle-docking units.
At the very bottom of the station was a docking bay for larger vessels. The well lit and expansive rectangular
entrance bay allowed easy entry to and launch from the structure.

The orbital office was only seen once, however the model was reused in Star Trek II: The Wrath of Khan,
flipped upside-down as Regula I laboratory. The model was used again in The Next
Generation and Deep Space Nine with the cylinder structures removed, most notably as
Starbase 375.
